Quality of Energy Provisioning for Wireless Power Transfer [PDF]

open access: yesIEEE Transactions on Parallel and Distributed Systems, 2015
One fundamental question for wireless power transfer technology is the energy provisioning problem, i.e., how to provide sufficient energy to mobile rechargeable nodes for their continuous operation. Most existing works overlooked the impacts of node speed and battery capacity. However, we find that if the constraints of node speed and battery capacity
